In an ideal world, customers love your brand so much that they tell everyone they know to use your product or service. For many years, marketing metrics have looked at influencers within a group and how they can get the brand message out to them. More recently, thanks to social media these influencers are even creating User Generated Content (UGC) that promotes the brand. The best example of this in 2014 has to be #ShareaCoke with the McGillicuddys.
